I have an image that has a white background but its also semi transparent so the white background seeps through. now if i remove the background it will still have the white parts where the original background was seeping through making it look really strange on any other background but white...
Is there a way to remove the "white" parts in the image...



The bottom of the img is exactly like something i have in mind (where the arrow is reflected and the arrows shadow as well)

As you can see when i remove background and change it to black it looks horrible:


Update:
I actually made a mistake by voting the first answer up. I want to know how to remove the background completely. I know how to save images so they are transparent

thanks to skids89 suggestion i figured it out. To remove a background from an image that appears transparent you need to:

cut out all the background that is not overlapping with the img. (magic wand select then del)

then you need to cut out all the places in the img that overlap with the background (using magic lasso tool or something similar) and paste them into a new layer

afterwards you need to apply the mask to the new layer and use the gradient tool just as skids89 suggested.(yet the img will still have the background behind it it will just be with a gradient and transparent) (changing opacity of the layer will also work)


now you need to create a background layer with a color opposite to the previous background color

and then you need to select the layer with the mask (not the mask the actual layer) go to image->adjustments->levels and move the bottom slider up

(that is if your color was white, otherwise first change channel setting to the most similar of your colors first--from RBG to blue for example if your bg was blue)
this will make your original background disappear :)

results (yours should look nicer if you applied gradient to it):


And this is how your final image will look like the bottom part having a truly transparent background so you can place any background behind it and it will look nice:


Tip:
If you have any jagged edges or dots left behind after the cutout
do the fallowing things to the layers with those problems:
create a mask for them
go to Filter->blur->Gaussian Blur mess with the value until the all the jagged edges are underlined (this might simply make it a tiny bit darker or transparent and might be hard to see but usually value somewhere around 2.0 works)
then go image->adjustments->levels
move the bottom slider up until the jagged edges are gone and move the top slider down until you are satisfied with the results. click ok and it should look wonderful
(if you not getting result expected you probably selected the layer instead of the mask undo all you've done and select the mask of that layer then try again)

Did you try a masking layer with a gradient applied to it? How it works cut out the arrow section where you want the color changeable and then set a background layer. Next create a masking layer for the reflected arrow and place a black to transparent gradient over it. I know this works in photoshop but I am unfamiliar with gimp's abilities.

I didn't read all of those tutorials but they seem to answer a different question.

If you want to save an image with a transparent background you need to remove the background from the image and then do "Save For Web" in either .png or .gif format and you'll have the ability to save with transparency. Then you can put it on any website and it will match the background.

For example:



Which should be saved like this:



Now, if you look on HTML you can see that as a transparent PNG you can put any background behind it:
